UNITED STATES PATENT OFFICE.

ISRAEL L. LANDIS, OF LANQASTER, PENNSYLVANIA.

MOTOR.

SPECIFICATION forming part of Letters Patent No. 250,265, dated November 29, 1881. Application filed May 5, 1881. (No model.)

To all whom it may concern:

Beit known that I, ISRAEL L. LANDIS, of Lancaster, in the county of Lancaster, and in the State of Pennsylvania, have invented certain new and useful Improvements in Motors; and I do hereby (leclare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

This invention relates to certain new and useful improvements in motors; and it has for its objects to provide an engine in which the liquid which supplies the motive power may be hermetically sealed, so that it cannot be lost, whereby the more volatile liquids may be employed which require but little heat to vaporize them, but which are too expensive to be wasted.

The present invention in one particular is also designed as an improved or modified form of constructing the continuous rim of the wheel over that construction shown in my previous application, filed April 1, 1881, for patent on improvements in motors. These objects I attain by the mechanism illustrated in the accompanying drawings, in which- Figure 1 represents a view, partly in section and partly in side elevation, of my improved apparatus; Fig. 2, a transverse vertical section and Fig. 3, a detached detail view, showing the arrangement of the pipes forming the spokes of the rotary motor-wheel.

The letter A indicates an annular chamber forming the periphery of the motor-wheel, and B a hollow shaft provided with journals 0.

The letter D indicates a series of hollow spokes. These are arranged to cross each other by being suitably curved at the center, as indicated in Figs. 2 and 3 of the drawings, and pass through the hollow shaft, to which they are secured. The said spokes extend into the chamberA, terminating in peripheral hemispherical recesses E, as indicated in Fig. 1 of the drawings. These hollow spokes are provided with apertures F, all opening in one and the same direction, and at each side of the several pipes in the annular chamber are located partitions G, which divide the annular chamber A into a series of compartments, as

indicated by the letter H. In some instances I contemplate putting the partitions Gr just in the rear of each spoke, in which casethey will bemadeofoneinsteadoftwopieces. Thesecompartments do not communicate successively with each other, butcommunicate diametrically in pairs, as indicated in Figs. 1 and 2, through the hollow spokes.

In carrying out my invention the chambers are exhausted of air, and each chamber is charged with sufficient fluid to fill the same, as shown in Fig. 1.

The apparatus is suitably mounted in supporting-journal bearin gs, so that the lower portion of the annular rim, as the motor revolves, travels through a tank of water, I, heated to a proper temperature.

The operation of my invention is as follows: Heat being applied to the tank I, the water therein is heated to about 130 to 14.0 Fahrenheit, when the liquid contained in the immersed portion of the apparatus begins to volatilize, creatingapressure uponthe surface of the liquid in each respective compartment, thereby causing the said liquid to ascend the communicating tube and flow through an aperture in the opposite end of the latter, discharging into its communicating chamber. By the time this action has taken place the wheel will have partially rotated, the rotation being the result of the change of position ofthe liquid, it having thus been transferred to the opposite side of the axis of the apparatus from which it started, thereby causing an overbalance of the wheel. This partial revolution of the wheel brings anothersection or chamber into contact with the heating agent, and then-the above operation is again repeated. Thus is a continuous revolution of the wheel obtained. When each spoke reaches a vertical position its contents are mostly vapor, as shown by the irregular lines in Fig.1of the drawings,which,

on the cooling of its communicating section,

becomes condensed, and finally returns to the bottom, forming a few drops of liquid.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In a motor or rotary engine, a subdivided annular hollow rim provided with peripheral hemispherical recesses adapted to receive the ends of communicating spokes, as shown and described.

' 2. The combinatiomin a motor or rotary engine, of the annular chamber A, hollow shatt B, provided with suitable journals, the hollow spokes D, crossing each other, as described, and having openings at their ends, and the compartments H, all constructed and arranged to operate substantially as and for the purposes 10 specified.

In testimony whereof I affix my signature, in presence of two witnesses,this 3d day of May, 1881.

ISRAEL L. LANDIS.
